Boor-TREEING MACHINE.

SPECIFICATION forming part of Letters Patent No. 289,044, dated November27, 1883.

Application filed March 1983.

To all whom it may con/cern:

Be it known that I, JOHN VARREN, of Bos ton, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Boot-'freeing Machines, of which the following, taken inconnection with the accompanying drawings, is especification.

ll/Iy invention relates to a machine for rub- 1o bing the exteriorsurfaces of boot-uppers in the operation technically known as treeing;and it consists in the employment of certain novel devices andcombinations and arrangements ofv parts, which will be readilyunderstood by reference to the description of the drawingaand to theclaims, to be hereinafter given.

Figure l of the drawings illust-rates a sectional elevation of a machineembodying my eo invention, the right-hand half of said figurerepresenting an elevation with the shank-rub hing wheel removed, and theleft-hand portion representing a central vertical section in a plane atright angles to the wheel-shaft. Fig.

2 is a central vert-ical section in a plane through the axis of thewheel-shaft. Fig. 3 is a partial section on line :c a" on Fig. 1,showing the position of one ofthe tlexible rubbers when in operationupon a bootleg with the tree 3o therein; and Fi g. A represents anelevation of the sh ank-rubbing wheel with the leather covering removedfrom the right-hand half thereoi'.

A is a column, provided with the base-flange A and the twoupwardly-projecting arms A A?, in the upper ends of which are formed thehearings A A3, in which is mounted the shaft B, having firmly securedupon one end the driving-pulley C and upon the other end the 4oshank-rubbing wheel D, as shown.

E E are two disks or wheels iitted to t-hc shaft B, between the bearingsA3 A3, in such a manner that they may be moved toward and from eachother upon said shaft, while they are compelled to revolve therewith.The hubs of the wheels E E have set therein keys or feathers a, whichalso fit into and slide in grooves formed in the shaft B in a well-knownman- 1 ner.

F is a spiral spring surrounding the shaft B, between the hubs of thewheels E E, and

(No model.)

acting thereon by its tension to force said wheels apart.

G G are two rings iitted loosel7 upon the shaft B, outside of the wheelsE, each in close proximity tothe hub of one of said wheels, and pivotedto the upper end ofone of the elbow shipper-levers II H, which leversare pivoted at Z1 b to ears c, formed upon the inner sides of the arms AA2, and forked at their upper ends, and provided with pivotal pins orcenters d to receive'the rings G G, as partially shown in Fig. 1. Thelever-arms of the shipper-levers II H project inward or toward eachother till they nearly meet, and are connected by the links e e and rodf to the treadle I, pivoted by its rear end within the column A, andprojecting through the slot g, cut ,through the front side of the columnA, as shown.

J is apawl-lever pivoted to the treadle-lever I, and arranged to engagewith the ratchetteeth 7L, formed upon the column A, on each side of theslot g, for the purpose of retaining the wheels E E at the requireddistance apart when they are moved inward by depressing the treadleleverI, to adapt them to a-ny particular job.

A series of leather tubes, K, are arranged at regular and equaldistances from each other around the peripheries of the wheels E E, withtheir central portions curved inA ward toward the shaft B, and their endportions radial thereto, said tubes being bent around grooved pulleys ii, mounted in slots formed in the peripheries ci' said wheels, and eachbeing connected at each end to a spring', j, the other end of which isconnected to a pin set in the hub of the wheel E, as shown in Fig. 2.The leather tubes K are filled with a core, k, of some ileXiblematerial-suoh as a cord oi' leather or textile material or powderedsoapstone-and have secured to each endthereof a metallic coupling, L,composed of the sleeve Z and plug Z', the latter being provided with theeye an, as a means of connecting the spring j thereto, and screwed intothe sleeve l, as shown. The greater part of the lengths of the sleeve Zand plug l are made tapering, or in the form of frustums of cones, andthe conical periphery of the plug Z is roughened by forming thereon ascrew-thread adapted to IOO ` purpose of preventing the tubes K frombeing ribs m of the wheels E E, and said pulleys are press it, and thusmove the wheels E E toward cutting it, as'shown in Fig. '2.

Thepulleys'i i are provided with journals which rest in slots formed inthe edges of the press into the leather of the tube K without preventedfrom leaving said bearings, in case of the breakage of a tube K whileAthe wheels E are in motion, by caps or guards over said journals, asshown at n in Fig. l.

An endless band or hoop, M, is fitted closely to and secured upon theperiphery of cach of the wheels E, as shown in Figs. l and 2, for thedisplaced from the pulleysz "i, said hoops being made preferably ofmetal and covered with leather.

The shank-rubbing wheel D consists of a plain circular metal disk, n,provided with a suitable central hub, and meansof securing it iirmly tothe shaft B, and having cast upon its outer radial face a series oflugs, n2 n2, upon each of which is secured a block of wood, o. the outerface of which is curved to the desired shape, as shown in Fig. 2.

The blocks of Wood o and the lugs n', with the beveled periphery ofthedisk, are covered with leather o', which is first molded to the desiredshape, then placed in position on the wheel D and secured thereto by themetal clampingrings p and q, secured to the wheel by suitable screws, asshown in Figs. 2 and 4.

The operation of my invention is as follows: The `boot beingstretched'upon the ordinary tree, the operator takes it in his hand and,holding it in the desired position in contact with one or more of theleather rubbing cords or tubes K, sets the shaft B in motion, to cansethewheels E E to revolve and bring each of the iiexible rubbers K intoaction upon the boot in succession, the operator meanwhile placing hisfoot upon the treadle-lever I to deeach other, and cause the flexiblerubbers K K to be bent around the boot to a greater or less extent as hepresses the boot toward the axis of the shaft B, and at the same timeturning the boot in his hands, as maybe required to present all parts ofthe boot-upper that can be touched by the rubbers K into position to beacted upon thereby.

In order to finish those portions of the upper in proximity to thesole-edge along the shank and fore part of the boot, the operatorapplies those parts of the boot to the action of the wheel D. By thismeans all parts of the boot may be acted upon by the machine, and

the treeingl may be completed without other hand-work than placing theboot upon and removing it from the tree.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

'lf In a machine for treeing b oots, oneor Amore iiexible rubbers in theforni of round cords or bands, arranged in planes radial to, andextending longitudinally of, and adapted to be revolved about an axis ofmotion, and to be bent or wrapped partially around the boot by contacttherewith, substantially as described.

2. In a machine fortreeing boots, a series of flexible rubbers in theform of round leather cords or straps, arranged in radial planes aroundand equidistant from a common axis,

about which they may be revolved, and adapted,

to be brought successively into contact with the boot to be treed, andto be bent partially? anism for moving the wheels E E toward and fromeach other, substantially as and for the purposes described.

5. 'Ihe combination of the shaft B, the Wheels E E, a series of flexiblerubbers, K K, a series of pulleys, il i, a series of springs, j j, thespring F, the two shipper-levers H H, connected to and adapted to movesaid wheels E E toward each other, the treadlc-lever I, and means ofconnecting said treadle to the levers H H, substantially as described.

6. The wheel D, composed of the metal disk n', provided with the lugs ofn, the wooden blocks o 0, leather coveringo, and the clampr ingrings pand q, all arranged and combined substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 20th day of March, A. D.1883.

JOHN XVARREN.
